Electric Circuits Flashcards
1
Q
Ohms law
A
The potential difference across a conductor is directly proportional to the current in the conductor at a constant temperature
2
Q
Adding resistor parallel
A
Resistance decreases
Current increase
Lost volts increase
Ext voltage decrease
3
Q
Adding resistor series
A
Resistance increase
Current decrease
Lost volts decrease
Vext increase
4
Q
Open switch
A
Emf = Potential difference
& no current in the Ext circuit
5
Q
Vext other names
A
Terminal potential difference /voltage
Vload
6
Q
Vint other names
A
Lost volts
7
Q
Emf
A
Energy provided by a battery per Coulomb passing through it.
